7 This invention relates to internal combustion engines and refers moreparticularly to the sleeve valve type of engine. In'this type of enginethe upper extremity of the sleeve ordinarily works ina pocket formedbetween the cylinder head and cylinder. While the -cylinderhead isordinarily jacketed for cooling water, the amount of available jacketingis limited due to'spark plug location and general arrangement of parts.As a result the sleeve jacket tends to'become overheated resulting information of steam pockets, carbon accumulation and general inefficientoperation of the engine. H V

One of the objects of my invention resides in providing meansforovercoming the above objectionable characteristics; To this end I haveprovided improved means associated with the cylinder head for causing apositive circulation of cooling water for cooling the cylinder head,sleeve pocketand-spark plug. 1 A further object of my'invention residesin the provision of means for supporting the seahng ring for thecylinder head and water jacket cover by the water circulation means.

I have provided a member preferably in the nature of a sheet metalstamping associated with the cylinderhead for assisting in guiding thewater in the desired circulating path sealing ring: Further features andadvantages of my invention reside in the simplicity of parts, lightnessof weight 'and abilityto be manufactured at low cost. One additionalfeature of my invention resides in the provision of a cylinder head havingintegrally formed radial baffles which extend down into the cylinderhead water jacket-space and alsoproject upwardlyfrom' this spacetodeflect the cooling water into the space. Such construction eliminatesthe ne cessity foraligning,- cooperating baffles carried by both thecylinder head and the cylinder head cover or other element. c 1'?Further features of my invention reside in the novel combination andarrangement of parts more particularly hereinafter described andclaimed. 7 Referring to the accompanylng drawings illustratin mvinvention and in which like reference characters indicate correspondingparts r i Fig.1 is a sectional elevation view through tion,

Fig. 2 is a perspectiveview showing the assembly of the watercirculating element with the cylinder head, 1 7 Fig. 3 is asectionalview of a cylinder head a typical engine cylinder showing myinventrating a modification of my invention, and

corresponding in general to Fig. 1, but illus- Fig. 4 is a perspectiveView of the cylinder head shown ,in-Fig. 3.

In the drawings reference character 10 represents an engine cylinderwith associated piston '11 and sleeve valve12, the latter forillustration being shown as the Burt-Mc- .Colliiin single sleeve valvetype in which the sleeve -is moved in a combined reciprocating andoscillating path with respectto the sleeve axis in moving sleeve ports13 to function with the cylinder-ports 14.

Thecylinder 10 is closed at the top by a cylinder head 15 whichis formedwith walls 16 andl'l'. The wall 16 together with the associated cylinderforms asleeve valve pocket 17 accommodating the movement of the upperportion of the'sleeve valve 12. The wall 17 is spaced from wall 16 toform the cylinder head cooling water j acket18 and also defines thecombustion chamber 19; The wallv 17 may be extended to provide a barrel20 with the spark plug opening 21; The cylinder head 15 may be securedto. the cylinder by studs 22 at the'corners ofthe cylinder head flange23. I I

cylinder by the side walls 28 and end walls 27, 30. A sealing ring 32surrounds barrel 20 and is supported by the top wall 29 of the member26, this sealing ring forming a. water seal joint between barrel 20 andthe cylinder head water jacket cover 33. For this purpose the cover 33has an opening 34 receiving the barrel 20, a nut 35 threaded on thebarrel serving to seat the cover 33 in position on the cylinderlO andalso serving to seatthe sealing'ring 32 on the member 26.

The cylinder head 10 has formed therewith the radial baflies 34 whichextend downwardly into the cylinder head jacket 18 but terminating shortof the bottom of the jacket.

In operation the water under pressure from the usual circulating pump(not shown) will pass mainly through opening 25 and will be guided bythe member 26 and baflies 34 so as to circulate downwardly into thecylinder head jacket 18'and upwardly thereof on the other side of thebaffles, thence through slots oropenings 36 in the member 26 to theoutlet header 37 which may lead to theusual cool.- ing radiator. (notshown). The member 26 also serves to seatthe sealing ring per mittingthe formation of a barrel 20 on cover 33 without the usualcircumferential sealing ring supporting flange as is customary atpresent. At the same time the parts may be readily assembled ordisassembled. i

Referring to Fig;- 3, the member 26 shown inFig. 1 is eliminated, thesealing ring 32 being seated by the flange 38 formed with the barrel 20as shown or with thecover 33 both being generally 'inv-useiat this time.In this instance the batHesS L-are constructed generallv as shown inFigsl and 2 the tops of the baflles being extended upwardly from flange23 sufliciently to deflect cooling water into the jacket 18. Theba'iil'es 34 extend upward-V flyto the-under side of the cover 33preferablyconneeting flange 38. In this modification generallyillustrated in Fig. 3' a single bafiie' vformed integrally with thecylinder head provides the circulation of. the cooling water downwardlyinto the cylinder head jacket, other cooperating baffles or waterguiding membersbeing dispensed with.

It will be apparent that in the embodiments of my invention shown inFigs. 1 and 3 each has its-advantages, certain advantages being commonas stated hereinbefore.
